What kind of fuel should i use in my 2002 honda accord se?

It's difficult to tell when VTEC engages. However, audibly, it's easier to tell if car is equipped w. aftermarket induction/headers/exhaust. Also, cars with oil pressure gauges will show slight pressure drop @ VTEC engagement since the system uses the engine's oil system to actuate the switchover to the high-lift cams..
